The pilot reported that, during approach the canopy opened, and he was distracted "because it was like a tornado in the plane." He attempted to hold the canopy closed and in the confusion the airplane impacted the ground short of the runway.
The airplane sustained substantial damage to the right wing.
According to FAA Aviation Safety Inspectors that examined the airplane after the accident, no mechanical malfunctions or anomalies were found with the canopy handle, latch, or the catch.
